18 Claims.

The present invention relates to improvements in typographical machines,and more particularly to those of the class shown and describedgenerally in U. S. Letters Patent No. 436,532 granted September 16,1890, wherein character bearing matrices stored in the appropriatechannels of a magazine are delivered therefrom and assembled into linesfrom which type bars or slugs are cast, after which the matrices arereturned by a distributor to the proper channels of the magazine fromwhich they were drawn, and the invention relates more especially to themore recently developed machines of this class adapted to hold aplurality of magazines, each containing a font of matrices, and from oneor another of which matrices may be drawn for assembly into lines.

As well known to those familiar with these machines, the matricescomprised within a given font are alike as to point size of the typecharacters thereon and as to style or face of the letters-or characters.To prevent delivery to the distributor, and consequently to a particularmagazine in use, of matrices of a point size differing from that of thefont in the particular magazine or magazines in use at the time, themachines are providedwith a so-called font distinguisher whichcooperates with font notches cut in the bottom edges of the matrices.The notching system comprises one or more point distinguishing notcheslocated at certain lateral positions alongthc bottom edges of thematrices to thereby designate the point size.

In addition to distinguishing the various. fonts ofimatrices from oneanother in respect to the size orfpoint of the characters there is theproblem of further distinguishing them. in respect to the style or faceof the characters, it being obvious that "matrices from a number offonts of the same point size, but belonging in different magazinesbecause they differ as to style or face, would pass a pointdistinguisher set forv the point size common to the several, fonts andthusibe distributed into the same magazine, thereby. resulting inconfusion, annoyance and loss of time due to a mixture ofwrong faces.

, ,While it haslbeen proposed to distinguish matrices as to style orface as ,well as point size by providing on the matricesadditionalnotches for face. distinguishing purposes and providingadditional distinguishers to cooperate with such notches, suchproposalhas been found impractical for the reason that it is not adaptable tostandard machines and matrices. To elucidate, there are many thousandsof matrix fonts in use.

\ each font comprising a complement. of twelve hundred or more matriceswhich have one or more point distinguishing notches in their bottom edgefor cooperation with the well known font distinguishers or fontseparators commonly employed on single and plural distributor machines,the latter being known as mixer machines in which matrices from twodifferent fonts, each stored in its own magazine, are composed in thesame line and, for separating purposes, require that the separatingnotches, better known as mixer notches, differ in location on thematrices of the respective fonts in order to in sure their return to theproper one of the two magazines which are simultaneously in use.

In view of the existence, according to standard practice, of these pointdistinguishing notches along the bottom edges of all matrices, itfollows that to be practical, any notching system which may be adoptedfor distinguishing as to style or' face mustbe suitable for applicationto existing-matrices as wellas new ones,,and must neither destroy norinterferewith the proper functioning of the established point notchingsystemh The prior proposal above referred to,'however, constitutes aradical departure from this standard as practice, it providing the pointnotch in a verti- I cal side .of each matrix instead of in the bottomedge,.a face notch in the same vertical: edge and another face notchinthe bottom edgeythelocation of one-face3notch being directly dependentjouponithe locationof the other Moreover, it was proposed to vary thedepth of the face notchin the vertical1edge,:but suchdeepernotches areimpractical for the reason that they seriously weaken the matrices sothat the lattermay' easily become distorted and: useless. i '1 i Theobject of the present invention is to, provideaifacenotchingysystemlwhich will be thoroughlypractical for the reasonthat it canbe applied toexisting matrix fonts andto new-fonts 4.;0 and will ,work,,in, completeharmony with the standard; point notching 1 system.; To thisend theinvention provides, in conjunction with the standard pointvdistinguishing notchesin the bottom edges of matrices, 1two face distinishing notcheswalso in the bottom edges, eachof the latter .notchesbeing independently variablein location in order to providethemaximumnumber of combinationslobtainable for use with each different point,notchlocation, Actually, aswill laterbe seen the face, nqtchingfsystem, according to the,present invention provides twentyone. face ,notch, combinations" for any one point notch amm nium other words, itenables twenty-one 'matrixffontsidiffering in style or face but 55 allof the same point size to be distinguished from each other. The fontdistinguisher blades necessary for cooperation with the notches involvedin this new system are, according to the present invention, entirelyindependent of one another and thus capable of individual relativeadjustment.

A further object of the invention is to provide for automaticindependent adjustment of the several font distinguisher bladeswhenever, a different matrix font is brought into operative position, toprovide for removal from operative position of any or all of the blades,and for protection against jamming or damage to any blade that may beengaged in a matrix notch, or to the mechanism associated therewith,should the magazines be shifted before the matrices undergoingdistribution at the time have cleared all of the blades. This lattersafety feature involves a yielding joint between the font distinguisherblades and devices in the form of gauge plates carried by the magazineswhich automatically control the adjustment of these blades.

To these and other ends, the invention consists in certain improvementsand combinations and arrangements of parts, all of which will behereinafter described, the features of novelty being pointed out moreparticularly in the claims at the end of this specification.

Similar parts are designated by the same reference characters in thedifferent figures.

The invention is shown by way of example as applied to a machine ofstandard construction such as that shown and described in U. S. LettersPatent No. 1,650,552, granted November 22, 1927, to J. R. Tomlin. Asshown, a plurality of magazines A are mounted in superimposed relationon separate base frames B secured together and supported as a movableunit in a frame C relative to Which they may be shifted fore and aft, inthis particular instance by a cycloidal motion ofthe magazine unit, theunit being supported on tracks D rigid with main frame E of the machine.vBy shifting the magazine unit one or another magazine, each containtiverelation at its upper end to the usual channel entrance F into which thematrices are delivered by the distributing mechanism and at its lowerend to the usual assembler entrance G into which the matrices fall whenreleased from the magazines in well known manner. While the design andarrangement of the gauge plates herein shown and described for adjustingthe several font distinguishers is specially suited to a magazine unitwhich partakes of the cycloidal motion above referred to when the unitis shifted, it will be apparent that the gauge plates may be altered inform and arrangement to suit rectilinear shifting motion, as employed inother type of machines.

Prior to entering the distributing mechanism the matrices pass through aso-called distributor box at the entrance of which, in the particularstyle of machine herein shown, there is located the font distinguisher.In another construction of these machines the font distinguisher or itsequivalent is located at the exit end of the distributor box. So far asthe present invention is concerned, however, it does not matter which ofthese locations is used so long as all of the distinguishers employedcooperate with the bottom edges only of the matrices.

Referring to Fig. 8 there is shown a matrix M of the usual form in thebottom edge of which, to the left of a vertical center line through theflat side of the matrix, is the usual point distinguishing notch MI. Inpractice this notch is located in different lateral positions in thebottom edge according to the point size of the font and in certaininstances additional notches may be employed for separating matrices oftwo different fonts used simultaneously as in the case on mixermachines. However, the actual number of point distinguishing notchesemployed in any font for separation according to point size of matricesbelonging to different fonts and the particular location of the pointnotch or notches along the bottom edge may be varied to suit differentrequirements.

For the purpose of describing the present invention it is sufiicient forthe moment to deal with the simplest form of matrix M having a singlepoint distinguishing notch Ml located at some point along the bottomedge of the matrix to the left of the center line hereinbeforementioned. According to the present invention there is provided in thebottom edge of this matrix, and to the right of thecenter line referredto, two face distinguishing notches M2, M3 as indicated in the matrix Iin Fig. 9. The relative positions of the notches M2 and M3, one to theother and of each to the point notch may be varied to form differentcombinations for the different matrix fonts according to the style ordesign of the type face represented by the particular font. Thus, thematrix I in Fig. 9 is representative of the location of the point andface distinguishing notches in all of the matrices comprising a font ofa given point size and a given style or face. The matrices 2 to 2|inclusive in Fig. 9 are each representative, as to the location of theirnotches, of all of the matrices of twenty other fonts differing from oneanother as to the style or design of the type face they represent, allof these fonts, however, being alike as to the point size of their typeface. In all there are twenty-one different fonts of matrices asindicated in Fig. 9, all of the fonts being of the same point size, asdesignated by the point notch Ml located in the same position in eachfont, but each font is of a different style or design of type face.Fonts of different point sizes will be indicated by different lateralpositions of the point notch Ml so that in each point size it will bepossible with the combination face notching system just described todistinguish between twenty-one different styles of type faces. Shouldone of the face distinguishing notches M2 or lVl--3 in a combinationselected for a given font correspond in location to a mixer point notchin an existing new font of matrices, such mixer notch will convenientlybecome part of the combination serving for face distinguishing purposes.

To cooperate with the matrices notched as described above there isprovided according to the invention three font distinguisher blades orrails 22, 23 and 24 which matrices undergoing distribution must passbefore they can enter the distributor which transports them in the usualman ner back to the magazines in which they are stored according tofont. These distinguisher blades preferably are arranged one in advanceof the other, see Fig. 2 and project into the path of matrices presentedto the distributor so as to register, with slight clearance, with thenotches in the bottom edges of the matrices. As previously stated thedistinguisher blades may be located wherever convenient in advance ofthe distributor and in the present instance they are located at theentrance end of the usual distributor box intowhich lines of matricesare delivered in well known manner.

The distinguisher blades are adjustable laterally across the path of thematrices presented thereto and it is proposed to provide for theirautomatic adjustment as by the known method of employing suitable platesor auges secured to the magazines and cooperating with a lever connectedto the font distinguisher. Since in the present instance there are threefont distinguishers, the distinguisher 22 being associated with thepoint distinguishing notch Ml and the distinguishers 23 and 24 beingassociated with the face distinguishing notches M-2 and M3 respectively,there are correspondingly three levers or lever systems for adjustingthe respective distinguishers, and each magazine carries a plate havingthree gauge "surfaces for actuating the respective lever systems. Themeans referred to for adjusting the several font distinguishers will nowbe described, it being important at this point to note that according tothe'present invention each of thedistinguisher's, 23and 24 for example.are entirely independent and adjustable relative to one another and tothe point distinguisher 22. To state it in another way, adjustment ofthe distinguisher 23 is in no way dependentup'onoraffected'bytheadjustment of the distinguisher 2 4and neitherof these'distinguishersare dependent upon the adjustment of the point distinguisher 22; v V I gThe distinguisher blades 22, 23 and .24 are mounted on 'shiftableslides'25, 26 and 2! respectively. "Each slide is supported freely onpins in the upper end of a lever and link for moving it horizontally andthe slides, levers and links are assembled as a unit on abracketcomprising fiat plates 28, 29 and 30'rigi ly secured together as bybolts30a.' 1

The 'slide25 carrying the pointdistinguisher blade 22 is providedwithpins or studs 3|, 32 which pivotally engage respectively a link 33and a lever 34, the link and lver being pivotally mounted on studs 35and 36 respectively. Slide 26 carrying the face 'distinguisher blade23is provided with pins 31, 38 pivotally engaging respectively a link 39and a lever 40, this link and lever being pivotally mounted on studs 4|and 42 respectively and between the plates 28 and 29. Slide 21 carryingthe face distinguisher blade 24 is provided with pins 43, 44 pivotallyengaging respectively a link 45 and a lever 45, this link and lever alsobeing pivotally mounted on studs 4| and 42 but between the plates 29 and3B.

As best shown in Fig. 2, slides 26 and 21 are provided with cam surfaces47 and 48 respectively which, upon sufficient leftward movement of theslides, ride under a fixed pin 49 passing through the plates 29 and 36].Such oamming action results in rocking the slides about the respectivepins 371 and 43 and retraction downward of the face distinguisher blades23 and 24 to an inoperative position. Elongated slots 50 and 5! in therespective levers 40 and 46 provide freedom for rocking movement of theslides, and springs 52, 53 secured at their lower ends to pins in theplates 29, 30 and at the upper end to pins in the respective slides,rock the slides back to operative position when the latter are movedsufficiently to the right to clear the pin 49.

Means is provided according to the present invention for independentlyand automatically moving each of the slides 25, 26 and 27 to therebylocate the respective point and face distinguisher blades 22, 23 and 24in predetermined operative positions, such means comprisingdevices'carried by each magazine indicative of the point size and thestyle or face of the matrices of the font contained in the magazine, andseparately operable yielding connections between said devices and therespective font distinguishers.

Referring particularly to Figs. l, 5 and 6, each magazine A is providedwith a gauge plate 54 removably secured thereto as by a screw 55, theplate being formed to overhang the left edge near the lower left handcorner of the magazine. The plates 54 are provided with a plurality ofgauge surfaces the locations of which vary according to the point sizeand style or face of the matrices contained in a particularmagazine."Ihus, the plate 54 shown by 'wayof example has three ledges 56, 5'! and58, ledge-i6 being indicative of the point size of the matrix font andledges 57 and 58 being indicative of the style or face of the fontcontained in the magazine. There are, of course, as many ledges'orgaugesurfaces on the plateasthere are distinguisher blades; the purpose ofthese ledges being to effect independent and automatic adjustment ofthedistinguisher blades to proper operative positions for registry withthe point and facedistinguishing notches in the matrices of differentfonts. The gauge plates; therefore, directlycontrol thesetting of thefont distinguisherbladesand automatically alter their setting each timea magazine containing a different font is *shiftedinto operativeposition on the machine. l

To effectadjustment of the font distinguishers in advanceof-thedistributing mechanismunder control ofthe' gauge plates onthemagazines there are provided three independently operable sets ofactuating connections. These connections comprise rods 59; fall andfilpivotally fastened at their upper ends to the respective levers 34, 40and 46 connected to the slides 25,25 and 21 and attheir lowerendsrespectively to crank arms 62,

63 and 64) The crankarrn 62 is pinned to a solid shaft 65 and the arms63 andii l 'arepinned tohollow shafts 66 and El respectively, the formerhollow shaft being free to rotate on shaft 65 and the latter hollowshaft rotating freely on shaft 66. These shafts are carried in a bearing68 on fixed frame C. To the inner end of shaft 55 is secured a crank arm69 and to the inner ends of the hollow shafts 66 and 61 are securedcrank arms 10 and II respectively. The crank arm 69 is disposed in suchposition that it will contact against gauge surface 56 on the undersideof the gauge plate 54 while a suitable stud or roller 12 in crank arm 10lies in position to contact against the gauge surface or ledge on gaugeplate 54 and a similar stud or roller 13 in crank arm II lies in suchposition that it will contact against the gauge surface or ledge 58 ongauge plate 54. A lug on each of the crank arms 69, I0 and H, see Fig.5, serves for securing to these arms respectively tension springs 69a, aand 1 la, each of which is secured at its outer end to a pin 14 in theframe C.

From the foregoing it will be evident that the gauge surfaces or ledgeson a gauge plate 54 of any magazine moved into operative position on themachine with the assembler entrance G and channel entrance F willcontact with and rock the crank arms 69, 10 and II which in turn,through rotation of the respective shafts to which these arms aresecured, will rock the crank arms 62, 63 and 64 respectively, thustransmitting motion to the respective levers 34, 40 and 46 by virtue ofthe rods 59, 60 and 6| extending between these levers and the lastabove-mentioned crank arms. As a result the slides 25, 26 and 21 and therespective distinguisher blades 22, 23 and 24 thereon will be moved intosuch operative positions as determined by the respective gauge surfaces56, 51 and 58 on the gauge plates 54.

In the absence of a magazine in operative position on the machine,springs 69a, 10a and Ha. will rock the connections comprising theaforementioned crank arms, rods and levers to the position shown in Fig.3. Here the point distinguisher 22 stands in an inoperative position asfar to the left as it is permitted to go as determined by a stop, notshown, the limit of its leftward movement being such as to block theentrance of matrices into the distributor when no magazine is inoperative position on the machine. As previously described suflicientleftward movement of the slides 26 and 21 results in retractiondownwardly of the face distinguisher blades 23 and 24 to an inoperativeposition, such retraction being effected by contact of the cam surfaces4! and 48 on the respective slides against pin 49. Thus, in the absenceof a magazine in operative position, springs 10a and I la acting on theconnections to slides 26 and 21 results in forcing these slides leftwardto the inoperative position shown in Figure 3 where the slides willremain until actuated by the introduction into operative position of amagazine and its gauge plate, whereupon crank arms 10 and II will bedepressed against the tension of springs 10a and 7 la to move therespective slides 26 and 21 to the right and clear of pin 49, springs 52and 53 rocking the slides into horizontal position.

Should the magazines be shifted and a magazine moved into operativeposition having differently located gauge surfaces for setting thedistinguisher blades, it will be evident that any blade still engagedwith matrices in the previous line would be subject to severe strain andpossible bending or damage to parts of the font distinguisher mechanism.To avoid the ill effects under these circumstances, the inventionprovides a yielding joint between the font distinguisher blades and thegauge plates carried by the magazines for adjusting the blades. Aconvenient construction for this purpose is shown in Fig. 7 wherein therod 60, for example, is shown divided and fitted with a sleeve securedto the lower portion thereof, a central longitudinal bore 16 in thesleeve accommodating the upper portion of the rod and the latter beingprovided with a Collar 17 of larger diameter than the bore 16 whichcollar reciprocates in a larger bore 18 concentric with the bore 16 andbears against a spring '79 seated in the bore 18. It will be evidentthat the overmotion in the rods 59, 6B and 6| permitted by thisconstruction will absorb any strain transmitted to the distinguisherblades in the event that one or another of the blades is engaged with amatrix at the time a magazine is moved into operative position which hasa gauge plate which does not conform to the adjustment of the blades forthe particular matrices undergoing distribution.
